The story of Citizenship Day
Whether citizens by birth or naturalization, Citizenship Day gives us the chance to celebrate the shared rights, responsibilities, and opportunities that unite us as Americans.
Observed annually on Sept. 17, Citizenship Day, also celebrated as Constitution Day, is a federal observance that honors two foundational pillars of American society: the signing of the U.S. Constitution on Sept. 17, 1787, and the recognition of all who hold U.S. citizenship.
A tradition through time
Supporters who wanted to establish Constitution Day began advocating for the day to be officially observed by the federal government over 100 years ago. Learn how Citizenship and Constitution Day began and evolved over the years.
1919: The National Security League first advocated for Constitution Day on Sept.17 to commemorate the day the Constitution was signed and to strengthen civic literacy.
1930: William Randolf Hearst—an American newspaper publisher and politician—advocates to establish "I Am an American Day" honoring new citizens during events across the country.
1940: “I Am an American Citizen Day” is formally recognized by President Franklin D. Roosevelt on the third Sunday in May to honor naturalized citizens and those coming into their civic responsibilities as adults.
1952: President Harry Truman signs legislation that shifts “I Am an American Day” to Sept. 17 and officially renames it Citizenship Day. Truman officially links Citizenship and Constitution Day in his remarks, stating that every American citizen should “give special thought and consideration to his rights and responsibilities under our Constitution” on this date.
2004: Congress established Constitution and Citizenship Day as a combined event, requiring all federally funded schools and agencies to offer constitutional education annually on Sept. 17.

The importance of Citizenship Day

Citizenship Day is an annual opportunity to reflect on the rights and responsibilities that come with being an American citizen. It’s a reminder that a strong democracy depends on citizens who participate in and serve their communities.
